I have spent hours on this!
+(NSMutableArray*)getStrings {
NSMutableDictionary* dict = [[NSMutableDictionary alloc] init];
[dict setValue: @"" forKey: [NSString stringWithString:@"one"]];
[dict setValue: @"" forKey: [NSString stringWithString:@"two"]];
NSMutableArray *array = [[NSMutableArray array] init];
This line should read: NSMutableArray *array = [[NSMutableArray
alloc] init];
This *may* be the cause of the problem.
NSEnumerator* keyEnum = [dict keyEnumerator];
NSString* key;
while ((key = [keyEnum nextObject])) {
[array addObject: key];
}
[dict release];
return [array autorelease];
}
// Here is where I call the above function
NSMutableArray* a =[StringHelper getStrings];
[a retain];
for(int i=0;i<a.count;i++) {
NSLog(@"> %@",(NSString*)[a objectAtIndex: i]);
You don't need to cast the object to NSString*. %@ works with any
subclass of NSObject.
}
[a release];
AFTER the code is complete I see the following message, the address
location is always the pointer to the array created in the
getStrings method.

message sent to deallocated instance 0x132950
Any help muchly appreciated. I have tried with and without the [a
retain] and [a release].
